Just to reiterate, you cannot store two different data types (i.e. an IEnumerable<Group> and an integer) using the same single data type (as C# is strongly typed). So you aren't going to be able to return one or the other unless you create a class that is used to store them.

Your best bet is going to be to return your collection (empty or otherwise) and then when you need to use the 0 value, simply check if your collection is empty and handle it there (but not within the current function).

You can use the below code to return zero if no match has been found

To return Sum as ‘0’ if no values are found, use IFNULL or COALESCE commands. The following is the syntax for IFNULL. SELECT IFNULL(SUM(NULL), 0) AS aliasName; Let us now implement the above syntax in the following query. Mysql SELECT IFNULL(SUM(NULL), 0) AS SUMOFTWO; The following is the output of the above query, which returns 0. From the Picture. I found result of sum -0. Please guide me result 0. I set format cell with Accounting.

This would sum each of the values of the records as opposed to actually returning the records.

A Where clause will never return null, at worst case there are no matches, in which it will return an empty collection (which won't trigger the null coalescing operator '??'). Additionally, this implies that assignedGroups could hold either an IEnumerable or an integer, which the compiler isn't going to allow.
